README

Production-ready multi-protocol microservice template built on HighPer Framework. Features TCP, QUIC support, protocol segregation, circuit breaker patterns, and serverless optimization with 2MB memory footprint and <10ms cold start. First release includes advanced protocol capabilities from day one.

🚀 Quick Start

# Install dependencies
composer install

# Basic HTTP server (HighPer framework compatible)
php server.php

# Multi-protocol server with TCP and protocol segregation
php server.php --tcp-enabled=true --protocol-segregation=true --non-secure-port=8080 --secure-port=8443

# High-reliability server with circuit breaker and retry patterns
php server.php --tcp-enabled=true --circuit-breaker=true --retry-enabled=true

# Development mode with full debugging
php server.php --host=127.0.0.1 --port=3000 --env=development --tcp-enabled=true

Performance Optimization

For optimal performance in microservice environments, install the php-uv extension:

# Ubuntu/Debian
sudo apt-get install libuv1-dev
sudo pecl install uv

# CentOS/RHEL
sudo yum install libuv-devel
sudo pecl install uv

# macOS
brew install libuv
sudo pecl install uv

# Add to php.ini
echo "extension=uv" >> /etc/php/8.3/cli/php.ini

Microservice Performance Benefits:

15-25% performance boost in high-concurrency scenarios
20-30% memory reduction in event loop operations
Better suited for containerized deployments
Improved response times for API endpoints

🔧 Customization & Examples

TCP Protocol Examples

Testing TCP Commands

# Start server with TCP enabled
php server.php --tcp-enabled=true --port=8080

# Test TCP commands using netcat
echo "PING" | nc localhost 8080        # Returns: PONG
echo "TIME" | nc localhost 8080        # Returns: TIME: 2024-01-01T12:00:00Z
echo "STATUS" | nc localhost 8080      # Returns: OK connections:1
echo "ECHO Hello World" | nc localhost 8080  # Returns: ECHO: Hello World
echo "QUIT" | nc localhost 8080        # Returns: GOODBYE

Protocol Segregation Example

# Start with protocol segregation
php server.php \
  --tcp-enabled=true \
  --protocol-segregation=true \
  --non-secure-port=8080 \
  --secure-port=8443 \
  --non-secure-protocols=http,tcp \
  --secure-protocols=https,tcp_tls

# Non-secure endpoints (port 8080)
curl http://localhost:8080/health
echo "PING" | nc localhost 8080

# Secure endpoints (port 8443) 
curl https://localhost:8443/health
# TCP with TLS would require TLS-enabled nc or openssl s_client

Circuit Breaker & Retry Example

# Start with reliability patterns
php server.php \
  --tcp-enabled=true \
  --circuit-breaker=true \
  --retry-enabled=true

# Monitor circuit breaker status
curl http://localhost:8080/health | jq '.configuration.circuit_breaker'

Extending the Nano Server

Extend the nano server by modifying the registerRoutes() function in server.php:

// Add custom routes
$router->addRoute('GET', '/custom', function(Request $request): Response {
    return new Response(200, ['Content-Type' => 'application/json'], 
        json_encode(['message' => 'Custom endpoint']));
});

// Add middleware-like functionality
$router->addRoute('POST', '/secure', function(Request $request): Response {
    // Add authentication logic here
    $authHeader = $request->getHeader('authorization');
    if (!$authHeader || !validateToken($authHeader)) {
        return new Response(401, ['Content-Type' => 'application/json'], 
            json_encode(['error' => 'Unauthorized']));
    }
    
    // Process request
    return new Response(200, ['Content-Type' => 'application/json'], 
        json_encode(['message' => 'Secure endpoint accessed']));
});
